Question

我有一个webapp，可以创建一些webgets并在Gridview中返回结果。有时，应用程序可能需要制作400多个网站，但只能在网格中填充15-20个记录。

是否可以部分加载GridView，以便将每条记录附加到现有GridView？

添加代码

    List<Test> testList = new List<Test>();
    foreach (Location str in list)
        {
            string url;
            try
            {
                url = "http://www.test.com/" + str.Url;

                XmlReader reader = XmlReader.Create(url);

                Rss10FeedFormatter formatter = new Rss10FeedFormatter();
                if (formatter.CanRead(reader))
                {
                    formatter.ReadFrom(reader);
                    IEnumerable<SyndicationItem> items = formatter.Feed.Items;

                    int itemCt = 1;
                    foreach (SyndicationItem item in items)
                    {
                            Test test = new Test();
                            test.Name = item.Name;
                            test.City= item.City;

                            testList.Add(data);


                            //if I add this here, the RowDatabound does not fire, if I take out, it works fine but only after all requests are made
                            listGrid.DataSource = temp;
                            listGrid.DataBind();


                    }
                }
                else
                    throw new ApplicationException("Invalid RSS 1.0 feed at " + FeedUrl.Text.Trim());
            }

创建一个单独的列表，您将DataBind到Gridview，然后每当您更改该列表中的元素时，只需重新绑定gridview。

var mySmallerList = bigList.Skip(someNumber).Take(someOtherNumber);
myGridView.DataSource = mySmallerList;
